Abstract
Control of the main gas stream from a compressor is accomplished by automatically adjusting the amount of gas vented from the compressor output by a variable relief valve or other flow restriction means, with the speed of the compressor being automatically adjusted to maintain the compressor output at a level permitting effective control within the useful range of the venting system. In a preferred embodiment, the amount by which the position of the means used to restrict flow through the vent conduit departs from a desired operating range is used to generate a compressor acceleration signal which is in turn used to generate a compressor speed set point signal from which the compressor speed is controlled.
